TRIPPING DEVICE.

Application filed November 26, 1918.

To all whom it may concern:

Be it known that I, JEssE Es'rnr, a citizen of the United States, residing at McRoberts, in the county of Letcher and State of Kentucky, have invented new and useful Improvements in Tripping Devices, of which the following is a specification.

This invention relates to tripping devices, especially designed for use in connection with double reversible aerial tramways, the.

object being to provide a device of this char-.

acter which is simple and durable of construction and positive in operation.

Another object of the invention is to provide a tripping device which may be readily secured to suspended cables at any desired point, so as to automatically trip and dump at a predetermined point, a bucket suspended from and traveling along the cables.

With the above and other objects in view, the invention consists of the following novel details of construction, combination and arrangement of parts, to be herein more fully described and illustrated in the accompany ing drawings.

In the drawings:

Figure 1 is a side elevation of a portion of an aerial tramway with the trip applied thereto, the latter being shown in the act of dumping a bucket.

Fig. 2 is a plan view of the supporting frame for the trip.

Fig. 3 is a side elevation.

Fig. 4 is a sectional view on the line H of Fig. 2.

Fig. 5 is an edge view of the tripper arm.

Referring in detail to the drawings, like characters of reference denote corresponding parts throughout the several views.

In the drawings the invention is shown as applied to a double reversible aerial tramway, which includes the spaced parallel cables 10, which are supported by any suitable means (not shown). These cables are designed to support and to provide means for transporting a bucket 11, the latter being supported from a carriage 12, by means of a hanger 13. The carriage and hanger may be of any usual or preferred construct1on and is designed to be drawn or propelled along the cable by any suitable means.

The trip, which is designed to be secured on any point along the cables for the purpose of tripping a bucket 11 and depositing its load at a predetermined point, lncludes a- Specification of Letters'latent.

frame and a trip bar, the latter being con nected to the former.

The frame comprises spaced parallel upper and lower I beams 14 and 15 respectively, which are connected together through the medium of standards 16, preferably located at each side and at each end of these beams. Also secured to the standards 16. are side beams 17, the latter being also in the form of I beams, and being bolted or riveted upon the outer sides of the standards parallel with the beams 14 and 15. Con nected to the outer ed es of the side beams 17, are hanger arms 18, which arms have their opposite upper ends connected to the stand ards 16, so as to secure the beams 17 rigidly thereto. To provide further rigidity for the frame diagonal braces 19 connect each of the standards 16 upon opposite sides of the beams 14; and 15.

One of the side beams 17 has its end flanges cut away at each end as shown at 20, and bolted to the web of the beam at these ends, is a saddle which is adapted to gripping the cable 10 to support the frame. This saddle comprises a substantially L shaped arm 21 which is provided at its outer extremity with a hook like terminal 22 for engagement over the cable 10. The saddle also includes an additional substantially L shaped arm 23, whose outer end terminates in a seat 24, adapted to engage beneath the cable. The arms 21 and 23 are secured to the beam 1'7 through the medium of bolts 25 which pass through both of said arms and through the beam, so that the outer extremities of the arms are clamped beneath and above the cable, forming a positive grip for securing the frame in position. As an additional securing means there is provided at each end of the upper I beam 14, an eye bolt 26, which is adapted to have secured thereto one end of a permanently anchored cable 27, the latter being securely anchored to some stationary point or object.

Bolted or otherwise secured to one of the beams 17, are spaced brackets 28. Pivotally mounted between these brackets, as shown at 29, is the upper endof a trip arm 30. The

lower end of this arm is preferably slightly ofi-set, and is provided along one of its edges with a plurality of engaging notches 31, which are adapted to engage a bar 32 carried by the bucket 11. This bar 32 controls the dumping of the bucket and when engaged by arm 30 will be locked in a manner to open the bucket and deposit its contents.

It will be seen from the foregoing description and the accompanying drawings that the invention provides a trip Which may be secured upon an aerial tramway at any de-' sired point so as to automatically dump the tram bucket when desired, the invention being especially designed for use in the handling of coal, so that the bucket may be gmptied any desired distance from the refuse The invention is susceptible of various changes in its form, proportions and minor details of construction and the right is here in reserved to make any changes that fall Within the scope of the claims hereto appended.

Having thus described the invention, What is claimed is:

1. A tripping device for aerial tramways embodying a frame, a removable saddle located at each end of the frame for engagement beneath the spaced cables, a hook also located at each end of the frame and engageable over the saddles to grip the cables, a trip arm depending from said frame in the path of a tram bucket, and means carried by said arm for engagement With the bucket.

2. A tripping device for aerial tramways embodying a pair of spaced parallel upper and lower beams, standards connecting said beams, parallel side beams connected to said standards and extending outwardly from each side thereof, means carried by the side beams for gripping spaced aerial cables, means for securing one of the ends of oppositely extending permanently anchored stay cables to one of said beams, and a tripper arm dependingfrom one of the'side beams.

In testimony whereof I aflix my signature.
